this is my main code and i could not stop this thread .
i want to stop it when i click the button b2(say cancel button).
the above code is not the original code and is a model , so please tell me how to stop that thread .
thankyou in advance . . . .
I have a alternate answer can try the same, inside your runnable loop always check a flag as run_flag, create it as a member variable and set it as true once you stared the loop, you can make it run_flag as false wenever you are done and at the same time you can set null to your thread also … a safer way to come out through runnable loop and thread.
